妥尔油酸二乙醇酰胺水基润滑添加剂的摩擦学性能Keywords: yanzj@dlmu.edu.cn. Abstract: 以精制妥尔油和二乙醇胺为主要原料合成妥尔油酸二乙醇酰胺,考察在原料摩尔配比为1∶1的混合条件下所生成的该类水基润滑添加剂的摩擦学性能.采用四球摩擦磨损试验机考察不同浓度添加剂极压、减磨性能;参照GB-T6144-2010对其pH、防锈性能进行测定.结果表明:妥尔油酸二乙醇酰胺可以极大提高水基极压性能,5%润滑液PB值高达1020 N;随着浓度增高,减磨特性增强, pH满足国标要求;浓度增加至3%后,防锈性能达到A级.Tall oleic acid diethanolamide was synthesized from refined tall oil and diethanolamine as main raw material mixed, and the tribological performance of its waterbased lubricant additive produced by mixing with molar ratio of 1∶1 was studied. The behaviors of extreme pressure and anti-attrition for different concentrations of additives were examined by testing on a four-ball tester, and the pH value and rust protection performance were measured according to GB-T6144-2010. Results show that water base extreme pressure performance can be improved by using tall oleic acid diethanolamide, and PB value is up to 1020 N for 5% lubricant, the higher concentration, the better the antifriction performance. pH meets the requirements of national standard, and rust protection reaches to A level as concentration up to 3%.
